I'm going to see if Ingalls Stiffy ETD will fit on my 2010 Mazda3. From what I've seen not much has changed between gen 1 and 2 MZ3's in respect to the layout of the Engine and suspension mount points.

I contacted them well over a week ago and still haven't received a response back... so being the impatient Guy I'm going for it anyway! Might see one up for sale in a while... or not

CorkSport motor mount inserts are my other option. They fill the open space in the transmission mount to limit movement. I've heard they are pretty harsh and transmit quite a bit of vibration, they are working on a lower durometer bushing...and are allot cheaper than the Stiffy but I can't stand the jerky/sloppy feel on acceleration from the squishy motor mounts anymore! So I'm taking my chances with Ingalls!

Update... the Ingalls Stiffy ETD does fit the new 2010 Mazda3's. I mocked it up loose and all the mounting points line up. Going to paint the brackets, and then wait for my Vacation to install it.

J'sMZ3, do you have pics of your install? What modifications did you make to the strut tower bracket? I would like to discuss your installation with you if you or anyone else has used our ETD on a 2010 MS3 or 3.
